Fixed NetHandler NetQueue memory leak.

Browse source 
TODO: Suspected memory leak somewhere in UDP.
Added early NetHandler detection for IPV6, just warns.
Implemented default: cases for NetHandler routines, warns and outputs unrecognized IPV4 procotols and ethertypes.
Added few more NetLog()'s for clarity.
